Functional Description
Applications
The GS82032 is a 2,097,152-bit high performance
synchronous SRAM with a 2-bit burst address counter.
Although of a type originally developed for Level 2 Cache
applications supporting high performance CPUs, the device
now finds application in synchronous SRAM applications
ranging from DSP main store to networking chip set support.
Controls
Addresses, data I/Os, chip enables (E
1
, E
2
, E
3
), address burst
control inputs (ADSP, ADSC, ADV), and write control inputs
(Bx, BW, GW) are synchronous and are controlled by a
positive-edge-triggered clock input (CK). Output enable (G)
and power down control (ZZ) are asynchronous inputs. Burst
cycles can be initiated with either ADSP or ADSC inputs. In
Burst mode, subsequent burst addresses are generated
internally and are controlled by ADV. The burst address
counter may be configured to count in either linear or
interleave order with the Linear Burst Order (LBO) input. The
Burst function need not be used. New addresses can be loaded
on every cycle with no degradation of chip performance.
Flow Through/Pipeline Reads
The function of the Data Output register can be controlled by
the user via the FT mode pin/bump (Pin 14 in the TQFP, Bump
1F in the FP-BGA). Holding the FT mode pin/bump low,
places the RAM in Flow Through mode, causing output data to
bypass the Data Output Register. Holding FT high places the
RAM in Pipeline mode, activating the rising-edge-triggered
Data Output Register.
SCD Pipelined Reads
The GS82032 is an SCD (Single Cycle Deselect) pipelined
synchronous SRAM. DCD (Dual Cycle Deselect) versions are
also available. SCD SRAMs pipeline deselect commands one
stage less than read commands. SCD RAMs begin turning off
their outputs immediately after the deselect command has been
captured in the input registers.
Byte Write and Global Write
Byte write operation is performed by using Byte Write enable
(BW) input combined with one or more individual byte write
signals (Bx). In addition, Global Write (GW) is available for
writing all bytes at one time, regardless of the byte write
control inputs.
Sleep Mode
Low power (Sleep mode) is attained through the assertion
(High) of the ZZ signal, or by stopping the clock (CK).
Memory data is retained during Sleep mode.
Core and Interface Voltages
The GS82032 operates on a 3.3 V power supply and all inputs/
outputs are 3.3 V- and 2.5 V-compatible. Separate output
power (V
DDQ
) pins are used to decouple output noise from the
internal circuit.

4. G is an asynchronous input. G can be driven high at any time to disable active output drivers. G low can only enable active drivers (shown
as "Q" in the Truth Table above).
5. All input combinations shown above are tested and supported. Input combinations shown in gray boxes need not be used to accomplish
basic synchronous or synchronous burst operations and may be avoided for simplicity.
6. Tying ADSP high and ADSC low allows simple non-burst synchronous operations. See BOLD items above.
7. Tying ADSP high and ADV low while using ADSC to load new addresses allows simple burst operations. See ITALIC items above.

Simplified State Diagram with G
Notes:
1. The diagram shows supported (tested) synchronous state transitions plus supported transitions that depend upon the use of G.
2. Use of "Dummy Reads" (Read Cycles with G High) may be used to make the transition from read cycles to write cycles without passing
through a deselect cycle. Dummy read cycles increment the address counter just like normal read cycles.
3. Transitions shown in gray tone assume G has been pulsed high long enough to turn the RAM's drivers off and for incoming data to meet
Data Input Set Up Time.

Application Tips
Single and Dual Cycle Deselect
SCD devices force the use of "dummy read cycles" (read cycles that are launched normally, but that are ended with the output
drivers inactive) in a fully synchronous environment. Dummy read cycles waste performance, but their use usually assures there
will be no bus contention in transitions from reads to writes or between banks of RAMs. DCD SRAMs do not waste bandwidth on
dummy cycles, and are logically simpler to manage in a multiple bank application (wait states need not be inserted at bank address
boundary crossings), but greater care must be exercised to avoid excessive bus contention.

Notes:
1. Customers requiring delivery in Tape and Reel should add the character "T" to the end of the part number. Example: GS82032T-100IT.
2. The speed column indicates the cycle frequency (MHz) of the device in Pipeline mode and the latency (ns) in Flow Through mode. Each
device is Pipeline/Flow Through mode-selectable by the user.
3. T
A
= C = Commercial Temperature Range. T
A
= I = Industrial Temperature Range.
4. GSI offers other versions this type of device in many different configurations and with a variety of different features, only some of which
are covered in this data sheet. See the GSI Technology web site(www.gsitechnology.com)for a complete listing of current offerings.
